A person is standing in an elevator. In which situation, he experiences weight loss ?

When the elevator moves upward with constant acceleration

When the elevator moves downward with constant acceleration

When the elevator moves upward with uniform velocity

When the elevator moves downward with uniform velocity

Answer and worked solution

Official answer: B

Apparent weight. $N=m(g-a)$ when the lift accelerates downward, less than $mg$ . Uniform velocity gives $N=mg$ ; upward acceleration gives more.
